SPECIFICATION forming part of Letters Patent N 0. 463,909, datedNovember 24, 1891.

Application filed January 18, 1889. Serial No. 296,720. (No model.)Patented in England March 2, 1888, No. 3,233; in France April 17, 1888,No. 190,032, and in Belgium May 1, 1888, No. 81,648.

To all whom it may concern.-

Be it known that I, FREDERICK MYERS, a citizen of the United States ofAmerica, residing at Liverpool, in the county of Lancaster, in theKingdom of England, have invent .ed certain new and useful Improvementsin Type-l/Vriting Machines, (for which I have received Letters Patent inFrance, No. 190,032, dated April 17, 1888; in Belgium No. 81,68, datedMay 1, 1888, and in England No. 3,233, dated March 2, 1888,) of whichthe following is a specification.

This invention relates to certain improvements in that class oftype-writers in which the type are arranged on the periphery of atype-wheel having a tendency to revolve under the action of a constantsource of power, but prevented from revolving by suitable mechanism,except when a type-key or its equivalent is depressed.

The objects of the improvement are to render such a machine moreefficient and easier to work and to enable it to turn out neater andbetter work.

The manner in which the invention maybe carried into effect may beunderstood by the following description, reference being had to theaccompanying drawings, in which Figure l is a front elevation of myimproved type-writing machine. Fig. 2 is a cross-section on line 00 50,Fig. 1, with the platen removed. Fig. 3 is an end elevation with keys,type-wheel, inking mechanism, &c., removed for the sake of clearness.Fig. 4 is a similar end elevation showing mechanism for inking the typeon typewheel. Fig. 5 is a plan of the upper portion of the machine. Fig.6 is a back elevation of a small portion of the key-frame with itshandle and connecting-rod for moving it longitudinally and a device forlocking it in the required position. Fig. 7 is a device for spacing thelines. Fig.8 is an, end elevation looking the reverse way to Figs. 3 and4., showing the self-winding mechanism, &c. Fig. 9 is aside elevation(enlarged) of disk with pins and stopping device for engaging the saidpins or projections. Fig. 10 is an end elevation of Fig. 9, and is usedalso as a diagram to sh w the arrangement of pins in the whole series ofdisks and ing Weight, a traveling band, the.

Fig. 14 is a view on device of the type-wheel, and Fig. 16 a view of thetype-wheel detached.

A is the main frame of the apparatus, on which are mounted the uprightframe 13 and the standard B.

A is the fixed machine-bed.

The main frame A, carrying the frame B, standard B, and almost the wholeof the mechanism, is pivoted to the fixed machinebed A at A the pivotspassing through the arms A extending from the lower front edge of themain frame.

0 is a wheel or disk, on the periphery of which are arranged, ashereinafter described, the letters, numbers, stops, symbols, &c., whichare required. mounted on a spindle or shaft D, which is journaled at oneend to the standard B and at the other to the frame B. The shaft D ispreferably driven by a spring, though other This type-wheel O is sourcesof motive power may be employed,

such as a small dynamo-machine, a descend- By preference I use a coiledspring F as a source of power. The shaft D and type-wheels arecontinually under the action of this spring, which is somewhat similarto those used for clocks, and is carried in the spring-barrel F on theend of the shaft D. It maybe rewound from time to time (as soon asit hasspentits force) by turning the barrel F by means of a suitable handle orprojection thereon. Instead, however, of rewinding it (after it has rundown) I prefer to keep it continually wound up by means of aself-Winding arrangement hereinafter described.

The keys G are arranged in parallel rows in the key-frame H. The samekeys which are used for printing the large characters may also be usedfor printing the small characters and the figures in the mannerhereinafter de- I00 scribed. The key-frame ll is mounted on guide-rods Eso as to slide longitudinally, the said rods being secured to the frame13 and standard B or in other convenient manner. Below each transverserow of keys there is provided a key-lever or rod J, which is pivotedloosely upon the spindle 0, carried by the sliding frame H, and uponwhich the keys G or their spindles rest. This key-leverean be depressedby any one of the keys G in the row which rest upon it.

The levers J are held in position, ashereinafter described, by means ofa spring J, Fig. 3, and, if desired,the keys themselves maybe providedwith springs. I prefer, however, to act upon the levers only with thespring or springs, so that all the keys in one row or the whole seriesof keys will descend when one key is depressed, and thus leave amplespace for the hand or fingers of the operator. The key-levers are madeof thin sheet metal, and are preferably guided in their downward courseby guiding-fingers J attached to the under side of the key-frame H.

All the keys are provided with shoulders or stops g so placed that notwo keys in a row will depress their leverJ to the same distance. Forexample, the first or back key may causeits lever to descend a littlefarther than the second, the second key a little farther than the third,and so on. Disks K are mounted in a rigid manner upon the spindle D, andbetween each of the said disks K, I mount two other similiar disks K Kwhich are also secured in a rigid manner to the spindle.

The spindle D, with its type-wheel (J, is prevented from revolving underthe action of the spring in barrel F by means of a stop-wheel M. Thiswheel is fixed on the type-wheel spindle, and preferably between thetype-wheel and the standard 13 of the machine. It is of slightly smallerdiameter than the type-wheel and has on its periphery a number ofwidemouthed nicks or holes on, formed by projections or pins m, or theirequivalent, and corresponding in number and relative angular position tothe type on the type-wheel. The stop-wheel, and therefore the shaft D,is held normally stationary by a movable catch or pawl L, which engagesone of the nicks m on its lower edge. This catch is carried by an arm N,which is pivoted at one end to the standard 13 of the machine, the otherend at being connected by an upright pivoted link at n to the outerextremity of the arm 0 forming one end of a rocking frame hereinafter tobe described. The aforesaid connecting-link n n is jointed at oraboutits center, as at it for reasons which will appear forthwith. Thearms 0 0 forming the ends of the rocking frame, are attached to thespindle O, which forms a pivot about the axis of which the frame mayoscillate. The remaining side of the frame is formed by a horizontal barP, fixed between the arms 0 and O and at or near their outer ends. Thebar P liesimmediatcly below the key-levers, and the latter rest upon andare supported by it, the frame itself being supported by the spring orsprings J aforesaid, connected to one or both arms O and to thekey-frame II. The frame 0 0 O P could, however, be pivoted at otherpoints besides those indicated. Each time a key is depressed thekey-lever J below it depresses the rocking frame by striking the bar Pcarried thereby. The frame in its turn depresses the link a n andcatch-arm N, and releases the stop-wheel M. The typewheel now revolvesunder the influence of the driving-power, being arrested, as hereinafterdescribed, bya small pin kin one of the disks K, K or K as soon as thepropertype is approximately in position for printing. The pawl M,pivoted to thestandard B above the stop-wheel, prevents any tendency ofthe latter to rebound when arrested, as hereinafter described. The wheelM having been released by the depression of a key, as aforesaid, anyfurther movement of the latter is prevented by the shoulder g strikingthe frame ll. On continuing the pressure the main frameA is caused toturn about its pivots A or rrying with it the type-wheel G and catch-armN. The latter immediately strikes a pin N fixed in the hinged bed S,hereinafter described. This causes the arm N to be raised and the catchL to beinserted into one of the wide-mouthed nicks in, so as to exactlyadjust and lock the type-wheel. The aforesaid movement of the arm ispermitted by the jointed link a 01 which bends about its pivot 72 butassumes its straightposition as soon as the key is released and therocking frame 0 O O P rises. The wheel M being looked, a furtherpressure on the type-key brings the type-wheel G into contactwith thepaper on the platen R, hereinafter described, the downward movement ofthe latter being slight in comparison with that of the wheel C. Thepressure on the key being removed, themain frame and its mechanism riseby reason of the spring A, Fig. 8, which is introduced between a flangea on the frame B and the fixed bed A. The spring is held in position bya core a at each end thereof. Theupward movement of the frame A iscontrolled by the adjustable stop a which is fitted with a buffer-block(0.

Instead of employing a direct pressure on the keys to depress the mainframe in order to lock the type-Wheel and to print, the fol lowingarrangement might be adopted: The entire machine might be mounted upon atable A, similar to the table of a sewing-ma chine, and below the saidtable an ordinary foot-treadle a might be placed, to which an uprightconnecting-rod a should be pivoted. The upper end of this rod would beattached to the hinged main frame A aforesaid, preferably at or near itsrear edge, as at 0. so that at each stroke of the treadle the main frameA would be depressed and the type-wheel C brought into contact with theprinting-platen R. On releasing the treadle the machine would beelevated as before by the spring A.

R is the platen, supported in any convenient manner on the frame R,which slidesin a hinged guide or bed S. The end of the platen R isprovided with a wheel having a number of notches r, Fig. 7, into which aspring pin or pawl r engages itself, holding the platen in any desiredposition. The distance between each of the notches r is equal to thedistance required between the lines of writing or printing. On thecompletion of a line the hand-wheel or disk N, Fig. 1, is turned in thedirection of the arrow, Fig. 7. The pawl r is therefore depressed andthe platen can be moved the required distance. One side of the bed S ishinged or pivoted at s to the main frame A of the machine and to theframe B or in other convenient manner. The other side is supported uponthe arm S which is preferably adjustable by means of the pin 3, carriedby the tail S of the hinged bed, or the whole of the hinged bed S may berigidly or ad justably attached to the fixed bed A.

Referring to Figs. 1 and 2, the depressing of the pivoted main frame Aalso causes the platen-frame R to be moved longitudinally the necessarydistance for spacing the letters. This may be effected as follows: Atoothed rack T is supported in brackets t, attached to the hinged bed S,and has at its end a pin t. The sliding frame R has pivoted to it a pawl29, which engages the teeth of the toothed rack T in one direction only.As the frame A is depressed by the depression of a key, the

rocking spacing-lever i pivoted at t to the frame 13, is also depressed.The tail end t of the lever 15 passes through a fork S Figs. 2 and 12,or its equivalent, carried by a block 8', which slides upon an uprightrod 5, loosely supported on the fixed bed A of the machine and in thebracket S on the frame B. The said block is unable to move upward beyonda certain point by reason of the fixed pin S but is capable of a varyingamount of downward movement, such movement being resisted to a certainextentby a spring S which tends to keep the block always in its elevatedposition, where it remains when the machine is at rest. n depressing themachine by means of a key G or the treadle aforesaid the tail t of thespacing-lever is held stationary by the lower branch of the fork of theblock S thus causing the lever to turn on its pivot t and to force theinclined finger Fig. 1, at its other end between the pint of thespacingrack and the side of the bracket 2. As soon as the rack hastraveled the required distance it is arrested, as will be hereinafterexplained, and any further downward movement of the pivot 75 causes thetail '6 of the spacing-lever to depress the forked block S in defianceof its spring 8. On the key or treadle being released after the letteris printed, the machine is elevated by the spring A, the block S risesto its upper position, and the tail t of the spacing-lever, catching theupper fork of the block, causes the inclined spacing-finger t to bewithdrawn, and the rack T is returned to its original position by spring15 The pins serve to limit the backward movement of the rack.

The type being of different widths, it becomes necessary when a neat anduniform spacing of the printed matter is a desideratum, to provide meanswhereby the printingplaten may be moved along through varying distances,according to the width of the character to be printed. If W, forinstance, requiredthe roller to be moved a distance equivalent to fiveteeth of the spacing-rack, I might only require it to be moved thedistance of one or two teeth. The varying spacing is accomplished asfollows: The teeth T of the spacing-rack are of such pitch that thespace required for each different width of letter correspondsapproximately to an integral number of teeth in the rack. Upon the rackis mounted a stop-arm or finger Q, Figs. 1, 3, and 13, which projectsupward between the type-wheel O and thestop-Wheel M and at a shortdistance from the face of the latter. On the said face, and preferablynear the periphery thereof, is a narrow raised annulus M the variouspoints in which are raised more or less from the face of the wheel, asshown in Fig. 1, according to the width of the characters on thetype-wheel, and have the same relative angular position as the saidcharacters. For instance, the projection of that portion, such as M ofthe annulus which would correspond to W (the Widest character) on thetype-\vh eel would be comparatively little, while the projection of theportion, such as M corresponding to I (the narrowest character) would becomparatively great. The actual difference between these projections(supposing W to equal five teeth on the rack and I to equal one tooth)would be a distance equal to four teeth, and the aforesaid stop-armwould stand normally, as in Fig. 1, at a distance of one tooth from thatpart of the annulus having the greatest projection beyond thewheel-face. In printing from left to right with this spacing device thecharacters on thetype-wheel are so arranged that all their right-handedges lie in a plane parallel to the face of the type-wheel. If a letter(say 1V) is to be printed, the type-wheel being placed in position bydepressing the key corresponding to thatletter, and the machine beingthen depressed, the inclined spacing-finger t draws the rack along asaforesaid until (after traveling a distance of, say, five teeth) it isarrested by the stop-arm comin g in contact with that portion of thesaid annulus, such as M which corresponds to the character in question.Any further movement of the spacing-lever is compensated, ashereinbefore explained, by the spring S Similarly the rack would bedrawn along a greater or less distance, according to the par- IIOticular part of the annulus against which the stop-arm would strike. Thestop-arm is preferably spring-pivoted to the rack at 1, so that it canmove in a direction transversely thereto. (See Figs. 1 and 13.) Eachtime the machine is depressed the stop-arm Qcomes in contact with thestop g on the catch-arm N or with some other abutment and turns slightlyupon its pivot, so that its upper extremity always moves approximatelyin the same vertical plane. g is the spring by which the stop-arm isreturned to its normal position. \Vhen the sliding frame R is to bewithdrawn, the pawl 25 may be thrown out of gear. If desired, the pawlst may engage the rack in a reverse direction, and the action of thesloping finger t and of the spring i may also be reversed, so as toactuate the frame R in the reverse direction.

For the purpose of spacing the wordsl provide an additional key V,having a foot '0, which when the key is depressed causes the slopingfinger t to engage the pin t on the end of the toothed rack T, and thismoves the printing-platen forward the necessary distance. This movementof the finger t is permitted by the tail if" of the spacing-lever byforming the latter with a spring toggle-joint 15 \Vhen the pressure isremoved from the key V, it flies up under the action of spring r, andthe finger t is withdrawn by the straightening of the tail under theaction of the spring of the toggle-joint. The rack T being thusreleased, it moves back, as before, under the action of the spring t",the pawl 15 riding over the teeth of therack. The spacing-keyV isdepressed by the pivoted lever V, having a pedal or fingerbar V which issupported at its other end on a similar pivoted lever V. By means of thefinger bar V the spacing-key V may be worked conveniently by eitherhand. The spacing-rack T can be drawn along to any suitable distance bydepressing the word-spacing lever, as the stop-arm Q is of such a lengththat it will not come in contact with the annulus M on the stop-wheelexcept when the said wheel is depressed by depressing the main frame A.The amount of travel of the rack when spacing a word is constantsayabout equal to five rack-teeth or the space required for a TV.

Any suitable stop may be provided for arresting the movement of the rackafter it has traveled the required distance for spacing a word. The pinst may for this purpose be made to engage the right-hand ends of theslots in the rack through which they pass; or the amount of projectionof the annulus M and the distance of the stop-arm Q, from the face ofthe wheel M may be such that the said face itself serves as a stop tolimit the movement of the rack.

The sheet of paper Q is held in position on the platen R by means of aroller 7", Figs. 1 and 3, which lies against the platen It. The roller0' is mounted between two arms 0- which are pivoted at r to the slidingframe R. The roller 1* is held in contact with the platen by a spring r,which presses against the arm 0- This arm has an extension 1, by meansof which the roller 4" may be drawn away from the platen B when thepaper Q is to be inserted or adjusted.

To fix a sheet of paper in the machine, the edge of the sheet is firstslipped under the platen B, being guided by the guide 9' The roller 0'is then thrown back, and the edge of the paper turned over the platenand held in position thereon by releasing the roller 9".

Each key-lever J is provided with a stopping device or plate j securedthereto, having projectionsj j, Fig. 9, at its end forengaging pins orprojections 7.; on the disks K K K attached to spindle D; or the disks KI 1' may be simple bosses provided with one or more arms having each astop-pin 7;.

()n the top of the frame B is a horizontal. spindle LL, Figs. 1, 6, and8, provided at the front end with a handle U, the other end being fittedwith a crank U. This crank is connected with the key-frame II by meansof a connecting-rod a. The key-frame can be moved longitudinally on theguide-rods E by means of the handle U, so that the projections ff on thestop-plate j will engage the pins 7.; on the disks K when the crank U isin the position shown in Fig. (3. \Vhen it is moved toward the left orright, the stop-plate j will engage, respectively, the disks K K Theframe is locked in the desired position by means of the pin 10 whichengages depressions or holes a in the spring-plate to.

The keys bearing their respective letters, figures, symbols, dye, may bearranged as shown on Fig. 5; but of course many other arrangements maybe adopted. To print large characters, &c., the key frame H is movedlongitudinally, so that all the stopplates j will engage the disks whoseprojections 7." correspond with the large characters on the type-wheel.Disks K may be conveniently used for the large characters. The first keyin the front row is, for example, depressed,which on Fig. 5 is markedwith the letter L until its shoulder g rests on the frame I'l. Itsmovement depresses the key-lever J and the rocking frame 0 O O P bymeans of the bar P thereof. The arm 0 of the said frame depresses thecatch-arm Nand releases the stop-wheel M, so that the stop-wheel willrotate under the action of the spring in barrel F. One of theprojections or of the stop-plate 7" will, however, engage a pin (markedL, Figs. 9 and 10) on the disk K corresponding to letter L on thetype-wheel, and will therefore instantly stop the motion of thetype-wheel G, the letter L on the said wheel being then approximatelyinaposition ready for making an impression on the surface of the paper onthe platen B. By afurther pressure on the key the wheel M is exactlyadjusted and locked in position, as before described. If the second keyin the same IIO row is depressed, which in the drawings is marked P, thestop-wheel is released as before; but the stop-plate] descends a greaterdistance than the first key, and therefore does not engage pin L, Figs.9 and 10, on the disk K, but a pin P, Figs. 9 and 10, corresponding tolarge P on the type-wheel. The remaining keys in the row stop thetypewheel in an exactly similar manner. As each key descends a greateror less distance the stopplate j can engage only one pin on the disk,and it is evident that the remaining pins cannot be engaged by it,because the proj ectionj or on its end is not of sufficient width toengage more than pinata time. The remaining rows of keys are arranged ina similar way; but it will be evident that the pins on one disk K arenot placed in the same angular position relatively to those on the otherdisks, but either lead or follow the pins thereon. If there are, forexample, as shown in the drawings, seventy-five characters on thetype-Wheel, and all the said characters are the same pitch or distanceapart, then the pins on each of the disks K K K will lead orfollow thepins on one of the other disks (preferably the one nearest to it) by anangle subtended by one seventy-fifth part of its circumference. (SeeFigs. 9 and 10.)

L P &, Figs. 9 and 10, represent, for example, the pins on the firstdisk K. Z AW represent the pins on the second disk K; X S E the pins onthe third disk K, and so on. I prefer to place the pins on each side ofthe disks and on the lines of two circles of different radii, Figs. 9and 10; but, if desired, the pins may be provided on one side only, orthey may be arranged on the lines of more than two circles. When thepins 7c are arranged only on one side of the disk, one projection j orjonly is required.

To print figures, the frame H is shifted on its guide-rods, so that thestop-plates j will engage the disks whose pins correspond with thefigures on the type-wheel, preferably the disks K There are generallyonly a limited number of symbols and figures required for general use,and therefore a limited number of pins will be required on these disks.The third and fourth keys in the first row are marked, for example, witha and 2, and there fore its disk will be provided with two pinscorresponding with the fraction and the numher 2 on the type-wheel.These pins are represented on Fig. 10 by T}- and 2. The second disk inaccordance with the arrangement of keys illustrated on Fig. 5, will beprovided with one pin, represented by 3 on Fig. 10, the

' fifth disk with two pins represented on Fig. 10

by 96, and so on. The first two keys in the first row, l and L, and thefirst three keys in the second rowflV A Z, will not engage anyprojection on disks K if they are depressed. The small plates g on therear key of each row are only provided for-convenience, as there isgenerally not sufficient space for the representation of more than onecharacter on a key.

To print small characters, the frame H may be shifted so that thestop-plates j engage the disks having pins in the same relative positionas the small characters on the typewheel, preferably the disks K Thefirst disk K will therefore have pins represented on Fig. 10 by 1, p,and &.

\V is a warning-bell, preferably attached to the hinged bed S. Thepivoted projecting pin or snug w actuates the hammer to each time theframe approaches the end of its travel, and thus indicates when the endof a line is nearly reached. The pawl t can then be raised and thepaper-roller drawn back to commence a fresh line of printing. The snugw, being'pivoted so as to turn in one direction only, actuates thehammer in the opposite direction. If it is desired to repeat theimpression of a character, the corresponding key may be again depressed,or the character may be repeated without the depression of the key andconsequent rotation of the typewheel by simply pressing upon the frame Hor on some portion of the pivoted frame A.

I ink the type previous to each impression asfollows: The ink is placedupon anabsorptive pad Y, Fig. 4, attached to a disk or plate Y, having astem Y The stem Y is carried by a socket y, forming the depending arm ofa bell-crank lever Y which is mounted loosely on the type-Wheel spindle,preferably between the type-wheel and stop-wheel. The other arm Y of thebell-crank is pivoted to the upper end of an oscillating link Y whoselower end is pivoted at Y to the fixed machine-bed A or other fixedpoint. Each time the machine is depressed the pad Y is drawn along thetype which is about to print and swung out of the way of thepaper-roller R. The stem Y is held in its socket by the spring device 11so that the pad Y just touches the type on wheel 0.

When a spring is used for driving the typewheel, it may be automaticallyrewound, as follows, (reference being had to Figs. 1, 8, and 15:) Oneend of the spring F is attached to the spindle D. The other end is fixedto the spring-barrel F. To take the weight of the spring-Windingmechanism off the shaft D, the barrel F is provided at one end with along journal or bearing-collar F Which fits over a stationary boss B onthe side of the frame B. On the end of this collar F is a ratchet-wheelf. The outer surface of the collar F between the barrel F and ratchet fforms a bearing for the suspension-eye of the heavy pendulum F. This eyecarries an arm F bearing a ratchet-pawl f which engages the ratchet Acheck-pawl is also provided, which prevents the return movement of theratchet and barrel. As the machine is oscillated about its pivots A thependulum swings to and fro, imparting a similar movement tothe pawl fThe latter intermittently rotates the ratchet-wheel f which, being inrigid connection with barrel F, winds up the spring F in the saidbarrel. I may ICC also, if desirable, apply an adjustable brake to thetype-wheel spindle to reduce the speed of the latter, and so to lessenthe concussion between the disk-pins 7.: and the stop plates or fingersjj carried by the type-key levers J; or instead of the pendulumarrangement for rewinding the spring the latter may be automaticallyrewound, as follows: either by the direct pressure on the keys G or bymeans of the treadle, as aforesaid.

The ratehet-pawlf instead of being mounted upon the end of the pendulum,is mounted upon an approximately horizontal arm F, Fig. 15, the eye ofwhich works freely on the collar F or other suitable pivot on or nearthe axis of said collar. The outer end of the arm F rests upon the upperend of a stiff spring F attached, as at f, tothebed or table A of themachine. As the machine is depressed the pawl-arm F, resting on thespringlinger, rotates slightly 011 the collar F, and thereby causes theratchet to be rotated in such a manner as to wind up the spring F.Should the spring be fully wound up, any subsequent depression of themachine causes the spring-finger F to bend or slip along the under sideof the pawl-arm.

The bottom of the hinged bed carrying the platen-frame is preferablymade telescopic, as shown at R Figs. 3 and 11, so that it may be drawnout and form an additional support to the overhanging frame R.

The details of the macl'iineherein described may be modified to acertain extent without departing from the scope of the invention.

I do not herein claim, broadly, a device such as the following: thecombination, with a type-wheel and a stop-wheel having both a constanttendency to revolve synchronously, of a catch device adapted to preventthe said wheels from revolving, a rocking frame connected with saidcatch device, and a series of type-keys, each adapted to depress thesaid frame and disconnect the catch device and its wheel, as asubstantially similar device is fully described and claimed in mypending applicatio11,Serial No. 263,189; nor doI lay any broad claim inthe present application to the following construction s,as suchconstructions are fullydescribed and claimed in my aforesaid pendingapplication, Serial No. 263,189: the combination, with the slidingplaten-frame, the reciprocatory feed-rack connected therewith, andthespacing-lever having an inclined finger adapted to engage the side ofa pin on said rack, of the spacing-key adapted to depress thesaid fingerandthe lever for operating said key; the combination of the power-driven type-wheel, the disks on the type-wheel shaft, the stop-pins 011said disks, the key-levers, and the stop-plates thereon; the combinationof the triple series of stop-disks, the sliding key-frame with its keys,levers, and stopplates, and the means for adjusting and hold ing theframe in any of its three positions; neither do I make any broadclaimfor the following devices, as substantially similar devices weredescribed in my pending application, Serial No. 263,189, and are old andwell-known constructions; the combination of the platen, slidingplaten-frame and hinged bed carrying the same, and the line-spacingmechanism, nor the combination of the sliding platen, the warning-bell,and the striking mechanism therefor.
